YII框架实现自定义第三方扩展操作示例
本文实例讲述了YII框架实现自定义第三方扩展操作。分享给大家供大家参考，具体如下：
cat.php
/**
* Created by PhpStorm.
* Date: 2016/5/25
* Time: 15:23
*/
namespace vendor\animal;
use \yii\base\Component;//组件
use \yii\base\Event;//
class myEvent extends Event{
public $message;
}
class Cat extends Component{
public function shout(){
echo "miao miao miao
";
//$this->trigger('miao');//事件命名
$me = new myEvent();
$me->message = "hello my Event
";
$this->trigger('miao',$me);
}
}
Dog.php
/**
* Created by PhpStorm.
* Date: 2016/5/25
* Time: 17:00
*/
namespace vendor\animal;
use frontend\behaviors\behavior1;
use yii\base\Component;//让一个类拥有接收行为的能力
class Dog extends Component{
public function behaviors(){
return [
Behavior1::className(),
];
}
public function look()
{
echo "I am looking!
";
}
}
Mouse.php
/**
* Created by PhpStorm.
* Date: 2016/5/25
* Time: 15:23
*/
namespace vendor\animal;
class Mouse{
public function run($e)
{
echo $e->message;
echo "I am running!
";
}
}
controllers/AnimalController.php 调用第三方类库
/**
* Created by PhpStorm.
* Date: 2016/5/25
* Time: 15:27
*/
//YII事件绑定
namespace frontend\controllers;
use yii;
use yii\web\Controller;
use vendor\animal\Cat;
use vendor\animal\Mouse;
use vendor\animal\Dog;
use \yii\base\Event;//类级别的事件绑定必须
use frontend\behaviors\Behavior1;//对象的混合
class AnimalController extends Controller{
public function actionIndex(){
$cat = new Cat();
$mouse = new Mouse();
$dog = new Dog();
//对象级别的事件绑定
$cat->on('miao',[$mouse,'run']);
$cat->on('miao',[$dog,'look']);
//
// $cat->off('miao',[$dog,'look']);//取消关注
//类级别的事件绑定
// Event::on(Cat::className(),'miao',[$mouse,'run']);//所有的老鼠都会监听这个miao事件
// Event::on(Cat::className(),'miao',function(){
// echo "miao event has triggerd!
";
// });
$cat->shout();
//\Yii::$app是YII实现的单例模式
// Yii::$app->on(\yii\base\Application::EVENT_AFTER_REQUEST,function(){
// echo "event after request";
// });
}
public function actionBehavior()//类的混合
{
/*板块1
* $dog = new Dog();
$dog->look();
$dog->eat();*/
$dog=new Dog();
$dog->trigger("wang");
}
public function actionObject()//对象的混合
{
$dog = new Dog();
$behavior1 = new Behavior1();
$dog->attachBehavior('beh1',$behavior1);//取个别名，防止冲突
//$dog->detachBehavior('beh1');//移除对象
$dog->eat();
}
}
